Class GraphQLObjectType

java.lang.Object

graphql.schema.GraphQLObjectType

All Implemented Interfaces:

GraphQLCompositeType, GraphQLDirectiveContainer, GraphQLFieldsContainer, GraphQLImplementingType, GraphQLNamedOutputType, GraphQLNamedSchemaElement, GraphQLNamedType, GraphQLNullableType, GraphQLOutputType, GraphQLSchemaElement, GraphQLType, GraphQLUnmodifiedType

@PublicApi
public class GraphQLObjectType
extends java.lang.Object
implements GraphQLNamedOutputType, GraphQLCompositeType, GraphQLUnmodifiedType, GraphQLNullableType, GraphQLDirectiveContainer, GraphQLImplementingType

This is the work horse type and represents an object with one or more field values that can be retrieved by the graphql system.

Those fields can themselves by object types and so on until you reach the leaf nodes of the type tree represented by GraphQLScalarTypes.

See http://graphql.org/learn/schema/#object-types-and-fields for more details on the concept.

Parameters:

name - the name

description - the description

interfaces - the possible interfaces

directives - the directives on this type element

definition - the AST definition

Method Detail

getDirectives

public java.util.List<GraphQLDirective> getDirectives()

Description copied from interface: GraphQLDirectiveContainer

This will return a list of all the directives that have been put on GraphQLNamedSchemaElement as a flat list, which may contain repeatable and non repeatable directives.

Specified by:

getDirectives in interface GraphQLDirectiveContainer

Returns:

a list of all the directives associated with this named schema element

getDirectivesByName

public java.util.Map<java.lang.String,GraphQLDirective> getDirectivesByName()

Description copied from interface: GraphQLDirectiveContainer

This will return a Map of the non repeatable directives that are associated with a GraphQLNamedSchemaElement. Any repeatable directives will be filtered out of this map.

Specified by:

getDirectivesByName in interface GraphQLDirectiveContainer

Returns:

a map of non repeatable directives by directive name.

getAllDirectivesByName

public java.util.Map<java.lang.String,java.util.List<GraphQLDirective>> getAllDirectivesByName()

Description copied from interface: GraphQLDirectiveContainer

This will return a Map of the all directives that are associated with a GraphQLNamedSchemaElement, including both repeatable and non repeatable directives.

Specified by:

getAllDirectivesByName in interface GraphQLDirectiveContainer

Returns:

a map of all directives by directive name

getDirective

public GraphQLDirective getDirective(java.lang.String directiveName)

Description copied from interface: GraphQLDirectiveContainer

Returns a non repeatable directive with the provided name. This will throw a AssertException if the directive is a repeatable directive that has more then one instance.

Specified by:

getDirective in interface GraphQLDirectiveContainer

Parameters:

directiveName - the name of the directive to retrieve

Returns:

the directive or null if there is not one with that name

getFieldDefinition

public GraphQLFieldDefinition getFieldDefinition(java.lang.String name)

Specified by:

getFieldDefinition in interface GraphQLFieldsContainer

getFieldDefinitions

public java.util.List<GraphQLFieldDefinition> getFieldDefinitions()

Specified by:

getFieldDefinitions in interface GraphQLFieldsContainer

getInterfaces

public java.util.List<GraphQLNamedOutputType> getInterfaces()

Specified by:

getInterfaces in interface GraphQLImplementingType

Returns:

This returns GraphQLInterface or GraphQLTypeReference instances, if the type references are not resolved yet. After they are resolved it contains only GraphQLInterface. Reference resolving happens when a full schema is built.

getDescription

public java.lang.String getDescription()

Specified by:

getDescription in interface GraphQLNamedSchemaElement

getName

public java.lang.String getName()

Specified by:

getName in interface GraphQLNamedSchemaElement

getDefinition

public ObjectTypeDefinition getDefinition()

Description copied from interface: GraphQLNamedSchemaElement

The AST Node this schema element is based on. Is null if the GraphQLSchema is not based on a SDL document. Some elements also have additional extension Nodes. See for example getExtensionDefinitions()

Specified by:

getDefinition in interface GraphQLNamedSchemaElement

Returns:

Node which this element is based on. Can be null.

getExtensionDefinitions

public java.util.List<ObjectTypeExtensionDefinition> getExtensionDefinitions()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

transform

public GraphQLObjectType transform(java.util.function.Consumer<GraphQLObjectType.Builder> builderConsumer)

This helps you transform the current GraphQLObjectType into another one by starting a builder with all the current values and allows you to transform it how you want.

Parameters:

builderConsumer - the consumer code that will be given a builder to transform

Returns:

a new object based on calling build on that builder

accept

public TraversalControl accept(TraverserContext<GraphQLSchemaElement> context,
                               GraphQLTypeVisitor visitor)

Specified by:

accept in interface GraphQLSchemaElement

public java.util.List<GraphQLSchemaElement> getChildren()

Specified by:

getChildren in interface GraphQLSchemaElement

getChildrenWithTypeReferences

public SchemaElementChildrenContainer getChildrenWithTypeReferences()

getChildrenWithTypeReferences in interface GraphQLSchemaElement

withNewChildren

public GraphQLSchemaElement withNewChildren(SchemaElementChildrenContainer newChildren)

Specified by:

withNewChildren in interface GraphQLSchemaElement

equals

public final boolean equals(java.lang.Object o)

No GraphQLSchemaElement implements `equals` because we need object identity to treat a GraphQLSchema as an abstract graph.

Specified by:

equals in interface GraphQLSchemaElement

Overrides:

equals in class java.lang.Object

Parameters:

o - the reference object with which to compare.

Returns:

true if this object is the same as the obj argument; false otherwise.

hashCode

public final int hashCode()

No GraphQLSchemaElement implements `equals/hashCode` because we need object identity to treat a GraphQLSchema as an abstract graph.

Specified by:

hashCode in interface GraphQLSchemaElement

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code value for this object.
